dahil quadratic equation po yan, cguro po gnito ang tamang pagkasulat ng equation, correctuon ko lang po ha... no offend po.
T^2 = 81.
Cge po. f ganyan po ang equation,. simple lang po yan.
step1. transpose 81 kya mapupunta po siya sa left side at machange yung sign into negative. parang ganito po. T^2 - 81 = 0
step 2. square root po ng T^2 is T.
step 3. square root ng 81 is 9.
step 4. Combine po lahat sa factoring.
Parang ganito po. (T+9) (T-9).
therefore, T = -9 and 9.

note: d po complete ang explaination kya feel free po to ask kung paano ko po nkuha yung mga sagot na sinabi ko.
hope it helps.

T² = 81

Solution:

 \sqrt{T ^{2} } =  \frac{+}{-}  \sqrt{81}

T = +9,  -9
